New Zealand Post Code Conversion

Postcodes have been used in New Zealand since 1977. Effective 1 June 2006, New Zealand Post introduced new postcodes and addressing formats. The new postcodes will create a unique address for every delivery point in New Zealand Post’s delivery network.

InfoAge can take your existing database and update the postal codes to the new NZ Post postal codes for Access database systems and small-medium workgroup systems were we can extract and import the data using Ctext files such as CSV or TAB delimited. Contact us for information and pricing.

New postcodes represent an important opportunity for New Zealand businesses. Not only will they enable organisations to improve the integrity of customer data, but they will help reduce the cost associated with undeliverable mail and improve customer satisfaction levels.

In order to receive bulk mail discounts (for batches over 300 mail items), customers will need to use new postcodes from 1 July 2008. To prove that correct postcodes (and other addressing formats) have been used, all bulk mail lodgements need to be accompanied by a Statement of Accuracy (SOA). An electronic SOA reports the address accuracy of a mailing list or database measured against the New Zealand Post Postal Address file (PAF). By 1 July 2008, accuracy of 85% must be achieved. The portion of mail below the 85% threshold will be charged at the full standard mail rate. The SOA will be progressively increased to 95% over time.

Every New Zealand postal address has a unique delivery point identifier (DPID) that ensures correctly addressed mail will always reach its destination on time. The new postcodes will replace the existing postcode system. As with the old system, the new postcodes will be four digits.

The first digit of the postcode represents one of ten machine 'lines' (numbered 0 - 9), which process mail for a specific geographic region. These run north to south in ascending order. The second and third digits reflect postal sort areas and our New Zealand Post delivery network i.e. urban posties, New Zealand Post PO Boxes, Private Bags and RuralPost. The fourth digit identifies the specific box lobby, rural delivery round or urban area.
